MACHINE FOR MAKING BRUSHES.

SPECIFICATION forming part of Letters Patent 1310344361, dated June 29, 1886.

Application liled Mareh 31, 1895. Serial No. 160,756. (No model.)

The dis- A series of bars, a, the same in number as tance of the pins 8 from each other in the rows the spaces between the pins 8 in the rows, are is governed by the number of strands used pivoted at their back ends to as many other 103 5c in making the brushes. bars, a, which swing on a bar held in the stand- The block E, holding the pins s, is connected ards that support the upper frame. The bars 2 v 3&4,361

a are so arranged as to come between the pins s s when they are brought forward, as shown in Fig. 4. When the bars a are not in use, they are swungbaclgand their front ends raised and held up by the hook-bar e". A creel, H, 1s placed back of the machine to hold spools, on which the strands o o are wound. The strands o are carried from the spools up over the rollers y y, and then down to the reed e,-

and through the spaces between the pins 3 s, to the front of the machine, forming what may be called the warp.

The operator, having previously placed one of the plates 8 between the two rows of pins 5 s underneath the strands, takes one of the strips of'wood p, and placing it over the back row of pins 8 presses it down on the strands between them. The treadle h is then pressed down, which, by means of the strap i, draws the frame (Z over to the front ofthe machine, (see dotted lines, Fig. 2,) bringing the strands in the reed with it, and doubling the strands over the piece of woodp just put on the back pins. He now places another of the strips of woodp over the front row of pins and presses it down on the strands between them, and, changing the power to the treadle h, draws down on the back part of the strap i, which throws the frame (Z over the pins toward the back, carrying the strands with it and doubling them over the strip of wood in front. This leaves the strandslying between the back pins ready for another strip of wood, as at first. These motions of the reed forward and back and the placing of the strips of wood are repeated until enough to form the proper width of the brush have been made. Then one of the plates 8 is placed between the rows of pins on top of the strands, and the bars aare unhooked, brought forward, and laid on the top plate 3 between the pins 8 s. The frame 0 is then raised up and hooked onto the projecting ends of the bars a, as shown in Fig. 4. The

operator then, by means of the hand-lever w, turns down the crank on shaft g, and thereby depressing the leverl and frame 0 compresses the strands on the pins 8 5 together with great force. While in this position a clamp, 0, is placed one on each end of the plates 8, and hooking over them, as shown in Fig. 5, to hold them together. The pressure is then removed by pushing back the hand-lever w. The frame 0 is taken from the bars a, which are swung back, raised, and secured by the hook-bar e. The hand-lever w is then pulled forward, and the leverb is depressed by means of the crank on the shaft f, which draws down the block E, pulling the pins 8 8 out of the brushes formed on them. The pair of brushes are then removed, retaining the plates and clamps on them, to keep them in shape until they are bound and otherwise finished, as described in my patent aforesaid. In making brushes with flexible backs the strips of wood are left out, and strands passing around'the pins 8 s are inserted in place of them.

Having thus described my improvements, what I claim as my invention is 1. In a machine for making brushes, the combination of the frame (1, reed 0, pins 8 s, and plate 3, substantially as and for the purpose set forth.

2. In combination with theframe d, reed 0. pins 8 s, and plate 8, the block E, lever b, and shaftf, substantially as described, for the purpose specified.

3. The combination, with the frame d, reed 6, pins 8 s, and plate s, of the bar a, frame 0, lever Z, and shaft 1 substantially as described, and for the purpose set forth.

4. The framed, reed 0, pins 8 s, and plate 8, in combination with the strap 1', and treadles h h.
